Pop Art emerged in the 1950s as a visual art movement that incorporated popular and mass media iconography into fine art. It reflected the optimism and consumerism of postwar society. Major Pop Artists like Andy Warhol, Roy Lichtenstein, and Claes Oldenburg used imagery and techniques from commercial art, advertising, and mass media to comment on the relationship between artistic expression and commodity culture. Their works employed recognizable symbols and objects in a style that was clear, colorful, and easily reproducible.
